Title: Ucheol Lee and Dynamic Edge Enhancement in Video.
Introduction
Ucheol Lee is an inventor associated with Ypsilanti, Michigan, and Visteon Global Technologies, Inc. His patent work addresses video display processing, with a focus on adapting edge enhancement to image content and ambient lighting.
Latest Patents
Lee is credited with 1 patent: “Dynamic Edge Enhancement in Video.” The invention describes a system that uses a light sensor, a circuit, and a microcontroller to improve edges in video displayed on a screen.
The circuit analyzes gray-shade values across multiple video frames, detects edges, and enhances them using a gray-shade transfer table and an edge-mask strength value. The microcontroller generates the transfer table from the video histogram and determines the edge-mask strength using the table, ambient-light measurements, and day and night luminance thresholds. The system then produces an output video signal suitable for driving the display.
Career Highlights
Lee’s listed patent reflects work on display technology and image processing. By combining video analysis with ambient-light sensing, the system is designed to adjust edge enhancement in response to both the content and viewing conditions.
Collaborations
Lee’s listed coworkers include Paul Fredrick Luther Weindorf and Brian J. Hayden. The available information identifies them as coworkers but does not specify their roles in the patent.
Conclusion
Ucheol Lee’s patent on dynamic edge enhancement presents an approach to adapting video processing to image characteristics and ambient lighting.
